Pump Shaft Quality

Stainless Steel Pump Shaft Quality (PSQ) Bars

Pump shaft quality bars completely ground to their finest to be distributed in rotating industries.

Pump ShaftPump shaft quality is found in stainless steel bars which are mostly used in shaft manufacturing including camshafts and crankshafts in automotive.

The pump shaft bars are manufactured with a higher standard than regular steel. Highly rigid requirements are from different factors:

Vibration – It is a big concern during spinning the shafts at a higher speed. This is why pump shafts require a super high degree of straightness to as much as possible, prevent damage and harmful vibrations during the machining.

Diameter – Diameter tolerance is a big standard in a bar. Pump shaft steels must have a diameter tolerance of less than 1” outer diameter to +0”; -0.002” and no less than 1.5” to 4.0” outer diameter. Thus, the diameter should be consistent and precise to fit the specific machinery for which it is designed.

Strength – Pump shafts should possess the high strength required in the application. Certain stages, especially in pump shaft applications undergo heavy loads and high speeds that might damage or stress the material. That is why pump shafts require exact specifications in their mechanical property with the possible tensile strength of 100 KSI and a minimum yield of 75 KSI.

Shipping – Pump shafts have a very critical nature that needs protection from a lot of damaging factors which include rough handling in shipping. Careful packaging should be used upon delivery and shipping such as wooden boxes and cardboard tubing.

Our Production Quality

We supply pump shaft quality bars ground to their tightest diametrical tolerance and perfect surface finish. The high tolerance that pump shaft quality bars have can help decrease wear and can provide products with more controlled properties. We have an inventory of steel bar products with pump shaft quality in random lengths. We work on meeting the explicit requests coming from our customers for their delivery requirements on an expedited accelerated basis.

Pump Shaft Stainless Steel Grades

Speaking of pump shaft steel, we supply the best stainless steel grades to be used in pump shaft application.

Our large inventory of PSQ products ranges from 1/2″ to 5″ in a variety of available steel grades. With the help of our centerless grinding operations, we can go on with our production of pump shaft quality steels.
